Cardiologists are begging you to never practice this mid-morning habit
Are you tired in the mid-morning? Experts advise not to reach for the caffeine. A second or third cup of coffee may not have the effect you hope it will. The stimulant can raise cortisol levels, which naturally dip around 10 or 11 a.m. Cortisol is the body's main stress hormone. It can also regulate inflammation and blood pressure and boost energy. But, high cortisol doesn't necessarily equate to high energy. 'Cortisol can be high and we can feel tired or low energy, like when we wake up. Or it can be low and we can feel high energy like the mid-morning. If I had to equate cortisol levels with something, it would be irritation,' Calm's Dr. Chris Mosunic said in a statement. Regardless, caffeine raises cortisol, 'potentially amplifying sympathetic tone," Dr. Marschall Runge told Parade. "[This] may heighten blood pressure or heart rate more than if caffeine is consumed earlier,' the cardiologist said. The sympathetic nervous system is a network of nerves that helps your body activate its 'fight-or-flight' response. Caffeine can raise sympathetic nerve activity and blood pressure. Previous research has shown people who drink coffee on a regular basis don't see that rise in blood pressure. "Until now we have attributed the cardiovascular effects of coffee to caffeine, but we found non-coffee drinkers given decaffeinated coffee also display these effects," Dr. Roberto Corti, a cardiologist at University Hospital in Zurich, explained in 2002. Some groups are especially vulnerable to mid-morning caffeine, according to Runge. They include people with anxiety disorders, those with a slower caffeine metabolism, women during their period or perimenopause, people with hypertension or prehypertension, individuals with a slow CYP1A2 gene variant, and people with known cardiovascular risks. If any of these groups repeatedly consume a second cup or an empty stomach during this period of day, they could see negative cumulative effects, he warned. "Repeated stimulation might stress the system over time," Runge warned. But, moderate caffeine use 'doesn't increase cardiovascular risk' and there are major benefits to drinking coffee. A recent study found it helped women age better. Between two to four cups of coffee a day should be safe. An eight-ounce cup contains close to 100 milligrams of caffeine. The U.S. Food and Drug Administration recommends no more than 400 milligrams of caffeine daily for adults. Notably, decaffeinated coffees are not caffeine free and everyone responds to caffeine differently. Beyond that — especially on an empty stomach — risks may increase. 'When your cortisol levels stay elevated, you're at an increased risk for weight gain, diabetes, heart problems and other health concerns,' dietitian Anthony DiMarino said. Eat well and regularly. Talk a short walk and make sure to stay hydrated — with water! "Dehydration often mimics fatigue," Runge noted.

Experts reveal side effects of having a second or third morning coffee
Experts advise against reaching for caffeine in the mid-morning, as it can raise cortisol levels, the body's main stress hormone, potentially heightening blood pressure or heart rate. Cardiologist Dr Marschall Runge warns that certain groups, such as people with anxiety, hypertension, or slow caffeine metabolism, are especially vulnerable to the negative cumulative effects of mid-morning caffeine consumption. Dr Roberto Corti's research indicates that the cardiovascular effects of coffee are not solely attributed to caffeine, as decaffeinated coffee displays similar effects. Dietitian Anthony DiMarino notes that elevated cortisol levels from excessive caffeine consumption can increase the risk of weight gain, diabetes, and heart problems. Moderate caffeine use (two to four cups of coffee daily) is generally safe and may even have benefits, but it's important to stay hydrated and avoid caffeine on an empty stomach to mitigate potential risks.
